21 Casino Review

21 Casino is a White Hat casino that’s been around since 2015.  The welcome offer speaks for itself!

21 Casino

The White Hat platform is well respected and was one of the first to be awarded a full UK Gambling Commission licence back in 2014 (yes! before a number of household names).  21 Casino itself has a very understated design showcasing the games against an almost plain background with just a hint of gold.

With a brilliant selection of games like they have at 21 Casino, who’s going to notice the background anyway?  There’s getting on for a hundred game providers listed in the lobby, so surely something for everyone!  Taking a look at the progressive jackpots gives an inkling of the range – there’s Red Tiger, Jackpot King, Dream Drop, Mega Moolah and WowPots plus several others.

Filtering games by the provider works correctly at 21 Casino (it doesn’t on some other casino platforms) and this is really helpful if you want to find games you haven’t played before and might like.  It doesn’t stop there though!

  1. On a desktop computer you can hover over a game tile in the lobby to see provider, number of reels, number of winlines and volatility rating.  The Return to Player isn’t shown, but it’s generally good at White Hat casinos (Book of Dead for example was set at the top rate of 96.21% at the time of writing, March 2024).
  2. Each game has “related tags” and “related features” to help you find similar games.  The tags are to do with theming and the features are, well, features.  For example, in the case of Immortal Romance Mega Moolah, the related tags include Bloodsuckers and Vampires and the related features include Jackpot and Spins Feature Choose and in the case of What The Fox Megaways, the related tags include Fox and Money and the related features include Bonus Wheel, Avalanche/cascading wins and Spins Feature Multiplier.
  3. If you still don’t know what to play there’s a Random Game button you can use, complete with a Try Again button if you don’t like what you get the first time,

All of this is a refreshing change from other casinos where you just have to browse through the game tiles and try to guess what they are like!

The live casino offering at 21 Casino is by Evolution, Pragmatic Play, Authentic Gaming and others with plenty of roulette, blackjack and game shows including Mega Ball, Vegas Ball Bonanza and Cash or Crash.  First person versions of Evolution games – Mega Ball,Dream Catcher, Craps, Lightning Roulette and others – appear in the table games area along with various other card game variants.

If 21 Casino has a weak area, it’s the promotions page where there seems to be nothing going on apart from the (very generous) welcome offer. Of course this doesn’t mean there are no other offers, just that they choose carefully which offers to send to which of their players.

21 Casino scores highly on game selection and usability, then, as well as on the quality of the welcome offer and on slot game RTP; if these are your top criteria when you’re looking for a place to play it is very definitely worth a visit.
